This NSE4 practice question tests your understanding of security profiles. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An administrator needs to block users from uploading files containing credit card numbers to external websites. Which TWO actions must be configured? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable SSL deep inspection on the firewall policy
Option B is correct because SSL deep inspection is required to decrypt HTTPS traffic so the firewall can inspect the content of encrypted uploads for sensitive data like credit card numbers. Without decryption, the DLP profile cannot see the payload of encrypted sessions, rendering the DLP sensor ineffective.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Apply an antivirus profile to the policy
Why it's wrong here
Antivirus scans for malware, not sensitive data.
✓
Enable SSL deep inspection on the firewall policy
Why this is correct
To inspect HTTPS uploads, SSL deep inspection is required to decrypt traffic.

✓
Create a DLP profile with a credit card number sensor set to block
Why this is correct
DLP can detect patterns like credit card numbers in file content and take action.

✗
Configure application control to block file transfer applications
Why it's wrong here
This blocks applications, not content within allowed applications.
✗
Use a web filter to block all upload websites
Why it's wrong here
Blocking upload sites is too broad and may impact legitimate use.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often forget that DLP requires SSL inspection to see the content of encrypted traffic, and mistakenly think a DLP profile alone is sufficient to block credit card numbers in HTTPS uploads.
Detailed technical explanation
How to think about this question
DLP sensors use regular expressions or checksums (e.g., Luhn algorithm) to match credit card number patterns in traffic. SSL inspection works by the firewall acting as a man-in-the-middle, re-encrypting traffic with a trusted CA certificate, allowing the DLP engine to scan decrypted HTTP/2 or HTTP/1.1 payloads. Without this, the firewall only sees encrypted TLS records and cannot apply content-based DLP rules.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the NSE4 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

What is the correct answer to this question?
The correct answer is: Enable SSL deep inspection on the firewall policy — Option B is correct because SSL deep inspection is required to decrypt HTTPS traffic so the firewall can inspect the content of encrypted uploads for sensitive data like credit card numbers. Without decryption, the DLP profile cannot see the payload of encrypted sessions, rendering the DLP sensor ineffective.
